Hello,

I am just starting using Yocto Project and I've been following along with the getting started section of the mega manual. I am working on Ubuntu 20.04 LTS through WSL2 on Windows 10 (not sure if it matters but I'm running OS build 20231) trying to create an image using poky-yocto-3.2.

I've followed all setup steps and made sure the host has all necessary packages before cloning poky (I kept running into an error when trying to clone the repo because the connection was refused so I just extracted the poky-yocto-3.2 tarball). When I try to run 'bitbake core-image-minimal' I get an error saying the following task failed with exit code 134:
'poky-yocto-3.2/meta/recipes-kernel/linux-libc-headers/linux-libc-headers_5.8.bb:do_install'
All the other recipes are installed with no problems.

The first time I tried this I changed local.conf in my build dir to build for qemuarm and next try I left everything as the default configuration but still got the same result. Any help fixing this issue is appreciated, thanks!

Could you share the command that you executed along with the full
output that was printed? There's not really enough information here to
diagnose the issue.

Thanks,

To be able to help you we'd need the logs of this task.
You can either paste the whole output on the console or send us the task
log you can find if you carefully read the console output.

Thanks for the quick response. I started out with a fresh clone of poky and only executed 2 commands:
1) 'source poky-yocto-3.2/oe-init-build-env'
2) in my build directory 'bitbake core-image-minimal'

The output from the console is:
aloof@LAPTOP-AQOIU06O:~/projects/yocto-test$ source poky-yocto-3.2/oe-init-build-env
You had no conf/local.conf file. This configuration file has therefore been
created for you with some default values. You may wish to edit it to, for
example, select a different MACHINE (target hardware). See conf/local.conf
for more information as common configuration options are commented.

You had no conf/bblayers.conf file. This configuration file has therefore been
created for you with some default values. To add additional metadata layers
into your configuration please add entries to conf/bblayers.conf.

The Yocto Project has extensive documentation about OE including a reference

### Shell environment set up for builds. ###

You can now run 'bitbake <target>'

Common targets are:
    core-image-minimal
    core-image-sato
    meta-toolchain
    meta-ide-support

You can also run generated qemu images with a command like 'runqemu qemux86'

Other commonly useful commands are:
 - 'devtool' and 'recipetool' handle common recipe tasks
 - 'bitbake-layers' handles common layer tasks
 - 'oe-pkgdata-util' handles common target package tasks

I'm not sure which log file. I'm attaching the one I found in the tmp directory. Is there a specific location you can point me to if this isn't the right log.

Hi,

I hit the same issue, also while trying things out on WSL2 (not committed enough to build a dedicated workstation/VM). I found a few more things:

This seems to be a pseudo abort with:

path mismatch [2 links]: ino 409763 db '/run/shm/sem.mp-bzdlrxrj' req '/run/shm/tGpqeT'.

I tried to follow the instructions to collect as many logs as possible. Logs are attached as far as I could find them; the strace is too big and you can find it here.

This is a regression: poky-3.1 (which uses linux-libc-headers 5.4) works. It seems we are not the only ones with this issue, and others have already given up on Yocto-on-WSL2.

Hope this is useful,
Matthias

One more thing: I tried reverting the linux-libc-headers version change (57d5f4ad410d4e9d55bdd9734bf5ab8fa6667a53) and that fails in the same way, so it's not that.

I also realized that the yocto-3.2 tag does not include the 3.2.1 updates; however the same issue happens on 3.2.1 as well.

I will try to bisect this but it seems like it will take a long time since I need to wipe the tmp directory at every step.
